4 Claims. (CL- 91- 68) This invention relates to a needled felt fabric designed for use as rug linings or carpet linings and particularly to a novel ,manner of providing such rug linings with a non-fraying edge. The

; invention, however, is not limited in its use to the making of rug or carpet linings but may be ap-' plied to needled felt fabrics designed for other purposes wherever it is necessary to provide a piece of such fabric with a non-fraying edge.

In the making of rug linings of needled felt it is the present practice to provide a piece of needled felt of the proper size to fit the rug with which it is to be used and then to bind the edge of the needled felt fabric so as to render it nonufraying by applying to the rug lining a row of relatively coarse stitches around the edge, such stitches frequently being of the type to overlie and enclose the marginal portion of the, rug lining.

In accordance with my present invention I provide the necessary binding for the edge of the rug lining by applying a binding material which is preferably waterproof and resilient to the edge faces of the rug lining as distinguished from the top and bottom faces thereof. Such binding material serves to bind together permanently the fibres of the needled felt fabric which are exposed at the edge faces of the rug lining and .thus

renders such edge faces nonfraying. I will pref erably employ a binding material which can be applied in liquid form and can, therefore, be sprayed onto the edge faces to be bound, the binding material having the characteristic that after it is thus sprayed it will set or harden thus -losing its liquid form and assuming a-solid form.

While various binding materials may be employed I.will preferably use a binding material containing rubber-and which when set or hard-- ened will not only be water resistant but will also have the desirable resilient qualities which will allow the edge of the rug lining to be compressed under pressure but will cause the edge to resume its natural thickness when the pressure is removed.

In order to give an understanding of the inven- -tion I have illustrated in the, drawing some selected embodiments thereof which will now be described after which the novel features will be pointed out' in the appended claims.

Fig. 1 is a perspective view of a rug lining made in accordance with my invention;

Fig. 2 shows one way in which the liquid binder may be applied to the edge faces of the rug lining; Fig. 3 is an enlarged section on the line 3-3,

material on the'edge face 5 cf the fabric.

In the drawing 1 indicates a piece of needled felt fabric designed to be used for a rug lining. when used for this purpose the fabric will have a size corresponding to that of the rug with which it is to be used, and as is well known, such rug linings are placed between the rug and" the floor to form a cushioned lining forthe rug. These needled felt fabrics are made from unspun fibre of some suitable character which is felted together by the needling process, that is, by passing a hat or web of such fibre through a needle loom. f

When used for rug lining it is necessary to bind the edges of the felt fabric so as to prevent the edges from fraying and so as to keep the edges in the proper shape. One way in which this has heretofore been done is to apply to the edge of the rug lining a line of stitching.

In accordance with my present invention Ipropose to provide the necessary edging for the lining by applying to the edge faces 5 a suitable binding material which will serve to bind together. the fibres exposed at said edge'faces and thus prevent the edge from fraying. By the term edge face I refer to the side edge facesof the so rug lining as distinguished from the top and bottom faces. While various binding materials may be used I prefer a binding material containing rubber in some form, either as latex or as a dispersion. Such a'binding material which has a self-vulcanizing characteristic is highly desirable, that is, arubber compound in liquid form which when exposed to theair will undergo a vulcanizing process as it dries and sets. because when such a binding material has dried and becomes vulcanized it will have the necessary resilient 'qualities but will not be tacky or sticky.

The binding material may. be applied to the edge faces of the rug lining in any appropriate way, such as spraying it thereon or passing the edge face of the rug lining over or in contact with a roll carrying thebinding material, or, in fact, in any other way which may be deemed advisable. Merely for the sake of illustration I have shown one way of applying the binding material in Fig. 2 wherein a plurality of rug linings 1 are placed one on the other with the edge faces 5 exposed and then the binding material is sprayed onto the exposed edge faces 5 by means of a r ying device 2. Such binding material which 105.

may be in the nature of a rubber latex or rubber dispersion, will penetrate into the needled felt fabric for 'a. limited distance as shown at 4 in Fig. '3 and will also form a coating of binding After the binding material has been thus sprayed or otherwise applied to'the edge faces of the rug lining it is allowed to dry or to set during which operation any water or volatile liquid constituent of the binder will evaporate thus leaving the rubber constituents which form the basis of the binding material that covers the binding together the fibres at the edge of the fabric and making said edge a non-fraying edge.

The operation of applying a binding to the edge of the rug lining in accordance with this invention can be accomplished at less expense'than that which is involved in sewing around the edge of the fabric and the binding embodying this invention is just as effective in preventing fraying of the edge as the, sewed binding. Furthermore, the bound edge of a rug lining embodying my invention is more resilient than the edge bound by stitches and, therefore, a rug lining made in accordance with this invention will not produce any line or mark on the upper face of the rug as the stitched binding frequently does.

I claim. A

1. The method of making a rug lining of needled felt fabric which consists in cutting the fabric to the required size, applying to the edge faces only of the rug lining a binding material containing rubber and allowing such binding material to dry or set thereby to provide a rug lining having its edge faces only coated with said binding material and having its top and bottom faces free from said binding material.

2. A rug lining made of needled felt fabric of appreciable thickness and provided with an edge face extending at substantially right angles to the top and bottom faces, said edge face having applied thereto a coating of binding material containing rubber the top and bottom faces being free from binding material. v

3. A rug lining made of needled felt fabric of appreciable thickness and provided with edge faces extending at substantially right angles to the top and bottom faces, said edge faces having applied thereto a coating of binding material containing rubber, the top and bottom faces of the fabric being free from binding material and said fabric having a uniform thickness from each edge face to the opposite edge face.

4. The method of making rug linings of needled felt fabric which consists of cutting a plurality of rug linings from a web of needled felt fabric, placing said rug linings in superposed relation with the edge faces in alignment, spraying a binding material containing rubber on the aligned edge faces of the stock of rug linings thereby producing individual rug linings, each having its edge faces only coated with the binding material and the top and bottom faces free from said binding material.
